Don't pay attention to the negative reviews on here--Fillaseat is a legitimate value. I've had my membership for two weeks (paid $36 on Groupon), and I've already gone to the Phoenix Symphony twice including the fabulous Star Wars vs. Star Trek show that sold out within minutes!! The people on here complaining that there's nothing but comedy clearly don't check the site very often. If you don't jump on deals, they disappear quickly. Of course they do!! Who doesn't want free tickets to awesome shows! You think there's an unlimited amount?
Here's what I do to ensure I get the best tickets--I put a direct link to the current events on my phone's home screen. Throughout the day--as I'm microwaving my coffee, giving my kids a bath, waiting in line at the grocery store--I hit it. Takes me straight to the current events and only takes about three seconds. This is how I've managed to get back about 400% of my money in tickets already. Also, I did notice that the Berlioz and Sibelius show was on there all week, so no one can say there's nothing but comedy. I've also noted several shows that I've no interest in, but are not comedy. Oh, and some WNBA stuff.
I'm excited to see what fabulous free tickets I can snag throughout the rest of the year! Don't believe the haters--the membership is totally worth it even if you only get one good show. You just have to be diligent in checking the site if you want the best stuff.
